How to increase volume on Xiaomi through the engineering menu: safe and risky ways

Have you ever encountered a situation where the maximum volume on your Xiaomi seems insufficient? You may be listening to music in a noisy place or watching videos without headphones, but the sound is still too quiet. Many users do not know that Android smartphones (including Redmi, POCO and Mi devices) have hidden settings that allow you to increase the volume beyond standard limits. One of the most effective ways is to use an engineering menu.

But before you start changing system settings, it's important to understand that it's not just volume settings, but the Engineering Mode gives you access to low-level settings on MediaTek or Qualcomm processors, where the wrong actions can damage speakers, distort sound, or even lose warranty. In this article, we'll look at how to safely turn up volume, which Xiaomi models support this method, and what to do if something goes wrong.

What is an engineering menu on Xiaomi and why it is necessary

The Engineering Menu (EngineerMode or MTK Engineering Mode) is a hidden settings section designed to test and debug the hardware of a smartphone.It is available on most Xiaomi devices with MediaTek chips (e.g. Redmi 9A, POCO M3) and some models on Qualcomm Snapdragon (e.g. Mi 10T, Redmi Note 10 Pro).

• 🔊 Customize volume levels for speakers, headphones and microphone.
• 📡 Test network, Wi-Fi, Bluetooth and GPS.
• 🔋 Check the status of the battery and charging.
• 🛠️ Calibrate sensors (gyroscope, accelerometer).

To increase volume, we are interested in the Hardware Testing → Audio section, where you can manually set Gain, which is the default manufacturer limit, but on some Xiaomi models (for example, Redmi Note 12 and later), the engineering menu may be blocked or hidden due to MIUI policy.

⚠️ Warning: Changing the settings in the engineering menu can cause speakers to overheat or distort the sound. On models with stereo speakers (for example, Xiaomi 13), incorrect settings can disable one of the speakers.

What Xiaomi models support volume change through the engineering menu

Not all Xiaomi smartphones allow you to change volume through the engineering menu.

• 📱 Processor: The most compatible devices on MediaTek Helio (e.g. Redmi) 9C, POCO C31). Snapdragon models (such as Mi 11) may have limited functionality.
• 🔄 Versions MIUI: Starting with MIUI 13, access to the engineering menu may be blocked. MIUI 12.5 and older odds are higher.
• 🔒 Flagship models (such as Xiaomi 14) are often denied this capability due to strict restrictions.

If your model is not listed in the table, try to log into the engineering menu below. If the menu is missing or the Audio section is not available, then the manufacturer has blocked this feature.

Step-by-step: how to enter the engineering menu on Xiaomi

To open the engineering menu, follow the following steps:

Make a backup copy of important data|Charge your phone at least 50%|Make sure the model supports the menu (see table above)|Prepare an access code (if required)-->

1. Open the Phone app and type in the combination: ##4636## Some models (e.g. Redmi Note 8 Pro) may have the code triggered: ##36446337###
2. If the combination didn’t work, try an alternative method: Go to Settings → About Phone. Press 7 times on the MIUI version to activate Developer Mode. Return to Settings → Additional → For Developers. Activate the OEM Unlock option (if available).
3. Once you log in, you'll see tabs like Information for phone data, Battery for battery information, Usage statistics for usage statistics, Hardware Testing for us.

⚠️ Note: Some firmware (e.g. Global) ROM for POCO X3 NFC) The engineering menu may require a password. The standard code is 1234 or 0000. If they don't fit, don't try to find a password, it can block the menu.

How to increase volume through the engineering menu: detailed setting

After you log in to Hardware Testing → Audio, you will see several sections.

• 🔈 Normal Mode - Standard mode (dynamics, headphones).
• 🎧 Headset Mode - Mode for headphones.
• 📞 LoudSpeaker Mode – loud communication.

Instructions for increasing volume:

1. Select Normal Mode (for the main speaker).
2. In the Type field, specify Media (for multimedia) or Ring (for calls).
3. Find Max Vol (maximum volume). Standard 150 or 160. Smoothly increase it to 170-180 (no higher!).
4. Click Set to save the changes.
5. Check the sound by playing the audio file. If there is wheezing or distortion, reduce the value by 5-10 units.

For headphones, repeat the steps in the Headset Mode section, where you can increase the Max Vol to 180-190, as the risk of damage is lower.

💡

Before you save the changes, listen to the test track at maximum volume. If the sound becomes "dirty" or intermittent, return the values to the standard.

Risks and Possible Problems with Volume Increase

Changing the parameters in the engineering menu is an interference with the hardware of the smartphone, and the consequences can be serious:

• 🔥 Overheating of speakers: Increasing Max Vol above 180 can cause membrane melting or amplifier failure.
• 🔇 Sound distortion: On cheap models (e.g. Redmi) 8A) even a slight increase in volume causes clipping (cutting the signal).
• 🚫 Loss of warranty: If the service center detects changes in the engineering menu, this may cause a denial of warranty repairs.

The most common problem is asymmetry (one speaker plays louder than another), which is typical of models with stereo sound (Xiaomi 11T, POCO F4), in which case you will have to manually balance the volume levels for the left and right channels.

Alternative ways to increase volume on Xiaomi without an engineering menu

If your model doesn’t support volume change through Engineer Mode or you don’t want to take risks, there are safer methods:

• 🎛️ Equalizer and sound effects: In Settings → Sound. → Select Preset Bass Boost or Volume on some models (e.g., Preset, POCO F3) Mi Sound Enhancer available.
• 🔊 Amplifiers: Volume Booster, Precise Volume or Wavelet allow you to increase the volume programmatically, but can cause distortions.
• 🔌 External speakers: Use a Bluetooth speaker or wired headphones with an amplifier (e.g. Xiaomi Hybrid Pro) HD).

For Xiaomi owners on Android 12+, there is another way to activate Dolby Atmos (available on some models in Settings → Sound → Dolby). This method does not increase physical volume, but improves the sound quality, making it clearer.

💡

The safest way is to use external devices (earphones, speakers) or software amplifiers, and changing the parameters in the engineering menu should be considered as a last resort.

Frequent Mistakes and How to Avoid Them

Many users make critical mistakes when working with the engineering menu, and here are the most common:

• ⚡ Too sharp increase Max Vol: Don't raise the value immediately to 200. Start with 160 and gradually increase by checking the sound.
• 🔀 Change in incomprehensible settings: Do not touch the Impedance or Mic Gain settings if you do not understand their purpose.
• 📱 Ignoring tests: Always check the sound after a change. If you have wheezing, return the standard values immediately.

Another mistake is trying to change the volume on custom firmware (such as LineageOS or Pixel Experience), which on unofficial assemblies, the engineering menu may not work properly or even be available at all.

⚠️ Attention: On models with AMOLED-With screens (such as the Xiaomi 12 Pro), high volume can cause the screen to vibrate due to resonance.
